Ginzburg-Landau theory of an RVB superconductor
V. N. Muthukumar, Z. Y. Weng
We present a Ginzburg-Landau formulation of the bosonic resonating valence bond (RVB) theory of superconductivity. The superconducting order parameter is characterized by phase vor…
Spectral function of the electron in a superconducting RVB state
V. N. Muthukumar, Z. Y. Weng, D. N. Sheng
We present a model calculation of the spectral function of an electron in a superconducting resonating valence bond (RVB) state. The RVB state, described by the phase-string mean f…
Localization transition in the Mermin model
Gregory Levine, V. N. Muthukumar
We study the dynamical properties of the Mermin model, a simple quantum dissipative model with a monochromatic environment, using analytical and numerical methods. Our numerical re…
Nature of Spin Excitations in Two-dimensional Mott Insulators: Undoped Cuprates and Other Materials
Chang-Ming Ho, V. N. Muthukumar, Masao Ogata +1
We investigate the excitation spectrum of a two-dimensional resonating valence bond (RVB) state. Treating the -flux phase with antiferromagnetic correlations as a variational g…
